Origin 8 quill stem

I just got one for cheap and installed it. Oddly it took a lot more effort to clamp the bar securely than it does with the stem I replace. Still I'm not sure the bar will stay in position with my body weight on it, I really had to use a lot more force than usual. I'm curious if any of you have installed these on any bikes and if your experience reflects mine. I put a little grease on the clamp area, which has never caused a problem, but wiping it off helped a bit. I am using a Scott Drop-in bar, if that makes any difference. Is this a sign that the stem is just a p.o.s. (it's just my everyday commuter/errand whatever bike)?

I've never tried the quill stem, but their threadless stems are quite cheap. They were a bit scary actually, from an amature engineering perspective. I'm talking about very sharp and thin angles at high stress points which are prone to cracking.

I rounded the edges, touched them up, with a metal file, so hopefully they won't crack.

I replaced the stem 1) for fit 2) reserve the nice stem for a nicer bike that isn't getting locked up outside. I'll see how it holds while standing up on a hill since I'm a big guy

oh, and the threads on the origin 8 stem did seem to be a bit shoddy, but that's compared to easton and deda offerings.
nothing to call home about.

Shim it!!

Origin 8 isn`t high end stuff but its not junk either. That stem is available in both 25.4 and 26.0 sizes and you probably bought the larger size. Your bars are available I believe in 26.4, 26.0 and 25.4mm diameters and sounds like you missmatched fits.

I am using 26.0 bar with the 26.0 stem, this is why I'm so confused. I know origin 8 isn't crap, I have used their products before and found them to be pretty good. Shimming for a tighter fit wont hurt, I guess. It's stupid that I have to do this when the product should fit on its own

One wrap of a beer/soda can might be enough. The specs are sometimes slightly off. Your bar may be slightly undersized and the stem slightly oversized, by just enough to make a difference.

An aluminum can adds ~0.3mm for each thickness. (Half Wrap= 0.3mm) (Full Wrap = 0.6mm) Pg

Well since your not sure how much clearance you need to make up, you should probably drink a few beers ahead of time to make sure you have enough pieces.

1 liter can of Sapporo

It seems the stem was brought closer to the bar diameter after initial installation, enough to barely let the piece of beer can get in there. I eventually got it in by twisting the bar and shim together into the stem. Still I am not so confident but I havent had a chance to take the bike out and test it on some hills. I'll put the previous bar I had on and compare.

So the bar that is not working with this stem is a Scott Drop-in. I swapped it for a Origin 8 Propulsion and now things are fitting as they should. It's a shame because I like the Scott bar.

So, the makeshift shim didn't work for the Scott bar?

Agreed - and probably a tolerance issue caused bu poor quality control. Some things about the 21st century really bug me. User generated content and user generated product reviews I can live wit - but QC based on customer feedback? Bicycle components are bad enough - but eventually some politician is going to be stupid enough to introduce that concept to nucular power plants.
